Support more options for when you highlight text

I found the feature for highlighting text very useful when I need to know the exchange rate from USD to CAD. I was actually highlighting everything thinking it would work but I ran into a few things that didn't work. For example I was highlighting this text for 35˚ and a feature like this could be added to show a temperature for celsius and fahrenheit. As well as earlier on I was highlighting another language hoping it would translate but that was a downer. I don't know how many currencies are supported but cryptocurrencies are a thought as well.

With all this said I'm hoping that everything will be supported with this highlighting feature once I saw this browser had this in the first place as well as the news feed I'm not going back to any other browser.
